SCUTTLE-OPERATING DEVICE.

SPECIFICATION :forrnling` part 0f Letters Patent No. 689,506, datedDecember 24, 1901. Applioationfled May 29, 1901. Serial No. 62,329. (Nomodel.)

To a/ZZ whom it may concern:

Beit known that 1, MARKUS MOLL, a citizen of the United States, residingat New York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Scuttle-OperatiugDevices, of which the following is a full and complete specication, suchas will enable those skilled in the art to which it appertains to makeand use the same.

The object of my invention is to provide a combined scuttle lifting andsecuring device by the use of which a scuttle may be raised or loweredfrom a distance and which when lowered into the closed position will beautomatically locked, so as to prevent opening of the same from theoutside.

To such ends my invention consists of a spring-catch coacting with asuitable hasp or similar device to lock the scuttle, a spring normallyforcing the catch into the locking position, a scuttle-lifting devicecomposed of a compound lever, means for actuating the lever mechanismfor moving the catch into the releasing position, and mechanism carriedby the lifting-lever for actuating the catch -actuatiug mechanism uponthe first movement of the scuttle-lifting lever, so as to release thecatch, all as hereinafter more fully shown and described.

In the accompanying drawings, forming part of this specification, inwhich like letters and numerals of reference designate correspondingparts in the several views, Figure 1 isaside view,in longitudinalvertical section, of a scuttle-casing with the scuttle locked inposition thereon, the same being provided with my improved combinedVscuttle lifting and securing device, the dotted lines showing thescuttle as it appears when in the raised position. Fig. 2 is a view ofthe scuttle and lifting mechanism shown iu Fig. 1, taken in section onthe line 2 2 thereof looking to the left. Fig. 3 is a view of thefastening or securing mechanism in section on the line 3 3 of said Fig.1 looking to the right. Fig. l is a view in detail on an enlarged scale,taken from the front side of the double-pivoted dog by the movement ofwhich the catch or securing device is operated; and Fig. 5 is a sideView indetail of the main lever with the pivoted dog actuating the dogshown in Fig. 4 connected with the same,

showing the manner of connecting the cord for actuating the entiredevice with such lever.

Referring to the drawings, A designates t-he rectangular framesurrounding the scuttle-opening, which is closed at the top by thescuttle B, which is hinged thereto at one end, as shown at C. Rigidlysecured to the side of the casing A, adjacent to the hinged end C of thescuttle, is a plate lO, to which is pivotally secured the bell-cranklever 1l, to the short end of which is pivotally connected theconnecting-rod 13, which is pivotally connected at the other end withthe scuttle B by a pivoted joint, as shown at 14. Pivoted to thebell-crank lever 11, on the longer arm thereof a short distance from thepivot-point 12 thereof, is a dog 15, normally forced toward the shortarm of the lever by a spring 16, and secured to this dog 15 is theactuating-cord F, which passes first through the hole 30 in the extremeend of the longer arm of the lever 1l, thence through two lead-rings 29,from the last of which it continues to the dog 15, to which it issecured at the upper outer movable end thereof, by which constructionupon the actuating-cord F being pulled down the lever 11 will not beactuated until the dog 15 has been drawn fully back. Located above theplate 10 and secured in a similar manner to the side wall of thesouttle-opening casing A is a plate 17, to which is pivotally secured bya pivot-pin 19 a downwardly-depending vibrating plate 18,

to the bottom of which is pivotally securedV the downwardly-dependingswinging dog 19', capable of being swung freely away from the hinged endof the scuttle, but when forced in the opposite direction toward suchhinged Y end by reason of its abutment against a projection 20 on theplate 18 always swinging such plate 1S toward the hinge C.

Secured to `the seattle-opening frame or casing A at the'end opposite tothe hinged end C is a plate 27, to which is pivoted a catch 25, keptnormallyin the securing position by a spring 28 and coacting with a hasp26, secured to the scuttle to lock the same in the closed position. Thiscatch 25 is moved int-o the releasing position, so as to bc free ofcontact with the hasp 26 by the action of the cord or wire 23, connectedwith a bell-crank lever 24, pivotally supported upon a suitable bracket29, which bell-crank lever is in opermeans of a cord or wire 22.

ative connection with'the pivot-plate 18 by By this arrangement it willbe seen that, the scuttle being closed and securely locked by the catch25A and hasp 26 in the position shown in Figs. 1 to f3, if now the cordF be pulled down the first pressure exerted thereon will draw thepivoted dog 15 to the left, and its end coming in contact with the lowerend of the dog 19 will force the saine against the projection 2O of theswinging plate 1S, whichv will thereby be forced to the left, and thismovement of the plate 18, exerted on the catch 25 through the medium ofthe wires 22 and 23 and bellcrank lever 24, will draw the catch 25 outof the hasp 26, and thus leave the scuttle B unlocked and capable ofb'eing lifted into the position shown in dotted lines in Fig. 1. As soonas the lever 15 has been drawn fully back the lever 11 will begin tomove downward, and this motion exerted upon the scuttle through theconnecting-rod 13 will lift the scuttle into the open position shown inthe dotted lines before referred to, in which it may be secured byproperly securing the end of the line F. When it is desired to close thescuttle, the cord F being .released from pressure, the scuttle will dropof its own weight, the dog 15 will swing back by the dog 19', which willswing freely back, so as to permit such passage, and the hasp 26 willforce the catch 25 back until the lip of such catch is able to enter thehole of the hasp, when the parts will be then in the position shown infull lines in Figs. 1 to 3.

Passing' through the end wall of the casing above the hinge C from theinterior, so as to project a short distance beyond the casingwall uponthe outside, as shown in Fig. 1, is a securing-pin 32, normally formedintegral with a plate 33, which is secured upon the inner side ofsuchend wall by suitable screws, (not shown,) and the end of the pin 32extends into a hole formed to receive it in the end piece of the scuttleB, and usually such hole is formed in and through a metallic plate 34.,screwed or otherwise firmly secured to the' inner side of such endpiece, and by .this construction it will be seen that the scuttle Whenclosed will be firmly locked at both ends and cannot be lifted andopened, even though the hinges C should be removed therefrom.

It is evident that many changes in and modifications of the constructionof my improved scuttle lifting and securing device may bev made withoutdeparting from the scope of my invention, and' I do not limit myself tothe exact formation of construction herein shown.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. In a device of the classdescribed, the combination with an automatic catch for locking thescuttle in a closed position, of a pivoted swinging plate, in actuatingconnection with the catch, a compound lever for lifting the scuttle intothe open position, means for actuating the lever, and mechanism carriedby the lever and actuated bythe lever-actuating mechanism for moving theswinging plate, substantially as shown and described. 2. In a device ofthe class described, the combination with an automatic catch for lockingthe scuttle inthe closed position, of a compound lever for lifting thescuttle into the open position, a swinging plate pivoted adjacent to thelever and in actuating connection with the catch, a dog carried by thelever adapted to be brought into actuating connection with the swingingplate, and means for first actuating the dog and afterward the lever,substantially as shown and described.

3. In a device of the class described, the combination with an automaticcatch for locking the scuttle in the closed position of a swinging platein actuating connection therewith, a dog pivoted thereto free to move inone direction and abutting against a projection of the plate on theother side so as to move such plate in unison therewith as the dog ismoved in that direction, a lever for lifting the scuttle into the openposition, a spring-retracted dog adapted to be brought into actuatingconnection with the dog carried by the swinging plate and pivoted to thescuttle-lifting lever, and means for moving the dog and afterward thelever, substantially as shown and described.

et. In a device of the class described, the combination withascuttlesecured to the scuttle-frame by a hinge, of a plate secured tothescuttle-frame adjacent to the free open swinging end thereof, aspring-catch pivoted to the plate, a hasp for the catch secured to thescuttle, a swinging plate pivotally supported by the scuttle-frameadjacent to the hinged end of the scuttle in actuating connection withthe catch, a downwardly-depending dog pivoted to the swinging plateabutting on one side against a projection on the swinging plate andcapable of free movement in the other direction, a bell-crank lever'having a short arm and a long arm pivoted to the scuttleframe, aconnecting-rod pivotally connected at one end to the short arm of thelever and at the other end to the scuttle, a swinging dog adapted tocoact with the pivoted dog of the swinging plateso as to move such dogand plate pivoted to the long arm of the lever, a spring for normallyforcing such dog in one direction, and a cord moving freely through ahole or lead in the extreme end of the long arm of the lever and securedto the dog for actuating the same, substantially as shown and described.
